speed
the speed loop is switched to P control. For the Servo Driver this mode is set at the factory as the
standard setting. The torque command level is set to 200%.
When P control switching is not used, and PI control is always used, the torque during acceleration
and deceleration may be saturated and the Servomotor speed may overshoot or undershoot. Using
P control switching suppresses torque saturation and eliminates Servomotor speed overshooting
and undershooting.

Sets the condition for switching the speed loop
from PI control to P control. Use Pn10C to
Pn10F to make the switching level settings.
Set when Pn10B.0 = 0 (switch using internal
torque command value). Set the conditions for
switching to P control using the ratio (%) of the
Servomotor rated torque. (Setting range: 0 to
800%)
Set when Pn10B.0 = 1 (switch using speed
command value). Set the speed (r/min.) to
switch to P control. (Setting range: 0 to
10,000 r/min)
Set when Pn10B.0 = 2 (switch using accelera-
tion command value). Set the acceleration (r/
min./s) to switch to P control. (Setting range: 0
to 30,000 r/min/s)
Set when Pn10B.0 = 3 (switch using deviation
pulse value). Set the deviation pulse value
(command unit) to switch to P control. (Setting
range: 0 to 10,000 command units)
